製品紹介
The Yokogawa AFS30D Duplexed Field Control ユニット (FCU) is a powerful and resilient control processor used in Yokogawa’s CENTUM VP Distributed Control System (DCS). Built with full redundancy—including CPU, power supply, and communication interfaces—the AFS30D ensures high system availability, fault tolerance, and uninterrupted operations in mission-critical industrial applications.
This model represents an enhanced version / the earlier AFS20D, /fering greater I/O capacity, improved processing performance, and tighter integration with modern field communication protocols like Vnet/IP, FOUNDATION Fieldbus, and HART. Designed for harsh environments and 24/7 process control, the AFS30D is particularly suited for oil and gas plants, chemical processing, power generation, and large-scale utility infrastructures where operational downtime is not an option.
